Patent JP-H01243328-A (JP)
Title: Buffer-type gas-blasted circuit breaker
Inventor: KASHIMURA KATSUICHI
IPC: H01H33/70
Filed: 1988-03-25
Abstract: PURPOSE:To prevent deterioration of a withstand voltage caused by decrease in gas density at the fore end of a fixed contact due to rapid gas flow by supplying high pressure gas to a chamber between first and second throat portions through a gas flowing-in portion when the second throat portion is broken by means of a large diameter portion. CONSTITUTION:Upon starting braking operation, movement of a small diameter portion 11a by means of a first throat portion 4a supplies high pressure gas passing through a gas flowing-in portion B as shown by an arrow 25. Substantial shutout of a large diameter portion 11c by means of a second throat portion 4b eliminates an exhaust area therebetween so as not to hardly form virtual gas flow. This can prevent any decrease in density at the fore end of a fixed contact 11 while maintaining the density in a preferable state. Therefore, even in such a case of breaking a small leading current that an arc between contacts 2 and 11 are lost while a high recovery voltage is applied therebetween, the gas density at the fore end of the contact 11 increases, thereby enhancing a withstand voltage.

Title: Automatic equalizer
Inventor: SAKURAI MASARU
IPC: H03H17/00
Filed: 1978-06-12
Abstract: PURPOSE: To improve unstableness and S/N basing upon a noise by providing a non-linear circuit compressed by a small signal to a signal path extending to a weight circuit after converting an error signal into a digital signal.  
     CONSTITUTION: Digital input data B 1  to B 9  are inputted from input terminal 20 and a group of analog switches are switched according to data B 1  to B 9  to connect constant-current supply group 25 to resistance ladder group 22, thereby developing a voltage converted an analog value at output terminal 21. Here, constant-current supplies 2I and 4I in group 25 serve as current supplies with the value, reducing resistance ladder 22 equivalently and the required precision of the resistance is eased which becomes stricter as the number of "bit"s increases. Then, connecting switch group 23 and logic circuit 26 completes a D/A converter whose output voltage is nearly zero while the input value is small and the increases as the input value increases. Consequently, even if the value of the digital memory changes around zero due to a noise, the variation of the output of the D/A converter is nearly zero.
